IMPROVEMENT IN APPARATUS FOR ATTACHING PUMPS TO BUNGS 0F BARRELSSpecification forming part ofLetters Patent No. 40,276, dated October13, 1863.

To all whom t may concern.'

Be it known that I, FRANCIS A. PRATT, of the city and county ofHartford, in the State of Connecticut, have invented a certain new anduseful Fastening for Barrel-Pumps; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making part of thisspecification, and to the letters of reference marked thereon, in which-Figure 1 represents a cross-section of a barrel with my inventionapplied thereto as a means of fastening for a rotary pump. Fig. 2 showsa side view of the apparatus. Fig. 3 is a plan of the same, and Figs. 4and 5 show, respectively, a side and end view of the lower part of thesuction-pipe of the pump.

Similar letters of reference denote the same part in the several gures.

My invention relates to an improved mode of securing to a barrel a pumpby which the contents of the barrel may be removed.

Previous to my invention the inconvenience and loss of time and power inpumping from barrels by portable pumps have been great, on account ofthe inefficient means which have been used to fasten the pump tothebarrel.

It is the object of myinventi'on to furnish a secure fastening for therigid suction-pipe of a pump in the bung-hole of a barrel which shallfirmly secure the said pump to the barrel in such a manner as to renderthe pump sufriciently steady to permit its being rapidly andadvantageously worked, and which shall be applicable to various sizes ofbarrels; and to these ends my said invention consists in the employmentof a conical sleeve applied to the rigid suction-pipe of a pump, theconical exterior surface of the said sleeve having a screw-thread cutthereon, or being provided with other equivalent means of forcing andholding it in the bung-hole of a barrel, in combination with aclamp-screw or an equivalent therefor for clamping the suction-pipefirmly within the sleeve, substantially as hereinafter clearly setforth; and my invention further consists in forming the end of thesuction-pipe of a pump into one or more sharp points capable ofpenetrating into the sides of a barrel, and thus holding the end of thepipe from slipping, in combination with a clamp for securing the pipe tothe bung-hole of the barrel, substantially as hereinafter described.

To enable others skilled in the art to make and use my invention, I Willproceed to a description thereof.

In the accompanying drawings, a represents the rigid suctionpi pe of apump, b. c is a sleeve which surrounds the said pipe and slides looselyupon it, except when clamped thereto in the manner hereinafterdescribed. The exterior ofthe sleeve c is of a tapering form, itsextreme lower end being of suitable size to enter the bung-hole of asmall barrel, while its upper or larger part is made sufiiciently largeto ill the bung-hole of a larger barrel. The taper of the sleeve may bemade to accommodate as great a range ot' sizes as may be deemed best.

A screw-thread is cnt upon the exterior conical surface of the sleeve c,so that the said sleeve may be screwed into the bung-hole of a barrel,B. (See Fig. l.) The threads of the screw-sleeve c will thus. be forcedinto the sides of the bung-hole, and the said sleeve be thereby iirmlyfastened into the hole, so that it can neither be shaken nor drawn out.Two projections, e e, formed on the upper end of the sleeve c, form awrench, by which it may be turned.

d is a set-screw tapped lthrough the side of the bushing or sleeve c insuch a manner that its point may be made to press against thesuction-pipe a of the pump, and thus clamp the pipe within the saidsleeve. By means of this clamp d the pump may be securedirmly to thebarrel when the sleeve is screwed into the bung-hole; but in order thatgreater steadiness may be insured, I form the end of the suction-pipetinto one or more sharp points, p, by cutting away the substance of thepipe in places, as shown in Figs. 4 and 5.. These points p may be madeto enter the wood on the inside of the barrel opposite to the bung-hole,and will thus steady the lower end of the pipe a.

The sleeve c may be forced into and held in the bunghole of the barrelby other means than by the screw-thread upon its surface-as, forexample, by hooked bolts the lower hooked ends of which may enter thebarrel and catch under the edge of the bung-hole, while nuts upon theupper ends of the said bolts and bearing on the top of the sleeve willserve to force the taperingv sleeve into the bung-hole; but this andother equivalent devices will come within the scope of my invention whenused in combination with the clamp-screw d, for the purpose specified.

Having described my invention, I disclaim the cutting away of the lowerend ofthe suction-pipe in the manner sometimes done to form passage-waysfor the liquids which are being pumped, except when the points aresharpened so as' to enter the wood of the barrel, and are used incombi-nation with a clamp for securing; the pipe in the bung-hole,substantially as described; but

What I claim, and desire lto secure by Letters Patent, is-

i 1. The employment, in combination with the FRANCIS A. PRATT.

In presence of WILLIAM RUSSELL, CHAs. C. SnULTAs.
